NEMA 12 and Nema 13 Pushbutton Enclosures are designed to prevent the ingress of dust, water, and oil. NEMA 12 electrical enclosures are constructed of carbon steel with a polyester powder coat finish and are most often used for indoor applications of automation control, including packaging, material handling, non-corrosive process control, and manufacturing. Gasketed doors protect the enclosure's contents from airborne contaminants and non-pressurized water and oil. Designed for all standard 30.5mm and miniature 22.5mm pushbuttons, switches and pilot lights.
Applications where corrosive materials and caustic cleaners are used, necessitate the use of a NEMA 4X enclosure. Applications include food, such as meat/ poultry processing facilities, where total washdown with disinfectants occur repeatedly and petro-chemical facilities, including offshore petroleum sites. AutomationDirect offers NEMA 4X Pushbutton Enclosures constructed from 304 stainless steel, 316L stainless steel, fiberglass-reinforced polyester, and polycarbonate.
